Check Digit Verification of cas no

The CAS Registry Mumber 29334-62-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,3 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29334-62:
(7*2)+(6*9)+(5*3)+(4*3)+(3*4)+(2*6)+(1*2)=121
121 % 10 = 1
So 29334-62-1 is a valid CAS Registry Number.

Baker's yeast-mediated regioselective reduction of 2,4-dinitroacylanilines: Synthesis of 2-substituted 6-nitrobenzimidazoles

Olguín, Luís F.,Jiménez-Estrada, Manuel,Bárzana, Eduardo,Navarro-Oca?a, Arturo

, p. 340 - 342 (2007/10/03)

Several 2,4-dinitro-N-acylanilines were regioselectively reduced at the C-2 position by baker's yeast in slightly basic media (pH = 7.5) to afford 2-amino-4-nitroacylanilines, which were then cyclized under acidic conditions to the corresponding 2-substituted-6-nitrobenzimidazoles. The benzimidazoles thus obtained can be employed as precursors for bioactive derivatives.
